Similar to vector matrix product, but different…

Hi, I don’t know what it is called, but I am looping for this functionality:

Give a vector with the same height as a matrix, find the matrix who’s row values are the matrix row values multiplied by the row value in the vector.

See attached image for a clearer explanation.

Is there an easy way to do this in MathCAD? I have found a work around, but it is not elegant.

Thanks

Oliver

You can do it in a small program

    Hi Fred,

    Thanks for that. Very neat.
    I was doing something similar in my work around, that involved using a loop. Its still a few lines though.
    Is there no way to do this in one line?

    Thanks

    Oliver

    Whats the reason you want it to be done in just one line/operation?

    Because you need it multiple times in your sheet?

    Then I would suggest you turn it into a user defined utility function:

      Werner, that is fantastic!

      Yes, I need to do it many many times in the same document.

      This is a perfect solution and will make it so much simpler, thank you!
